The structure that receives vibrations from stapes and sends them to the cochlea?

Explanation:
Vibrations travel from the eardrum through the chain of middle-ear bones to the stapes, which presses on the oval window. From there, the energy enters the inner ear as fluid waves in the vestibule, the entry chamber that connects to the cochlea. The vestibule then channels these vibrations into the cochlea, where they are eventually converted into neural signals. The malleus is an earlier link in the chain, the Eustachian tube just equalizes pressure, and the cochlea is where the signal is transduced, not the structure that first receives stapes vibrations.
